While its PayPal payment system has been driving eBay's growth for years, the company is also trying to lift its more familiar marketplaces unit. The unit, a high-margin but mature business that connects online buyers and sellers, accounted for 62.5 percent of eBay's sales last year.

The president of the marketplaces unit left the company in September, but that has not prevented Chief Executive Officer John Donahoe from making deals while he looks for her replacement, Gillis said.

He needs to get the marketplaces turned around in order to be seen as a successful CEO, Gillis said.

EBay said that it did not expect the transaction to affect the 2011 profit outlook it gave last month and anticipated the deal would close in the second quarter, subject to regulatory approval.

The company, which generated about 54 percent of its 2010 revenue of $9.16 billion outside the United States, has made other overseas deals. In December, it bought Germany's brands4friends for $200 million.

GittiGidiyor has 6.4 million registered users in Turkey and employs 150 people. At the end of 2010, eBay had 94.5 million registered users.

Shares of eBay were down 1.6 percent at $30.69 in morning Nasdaq trading.
